Phlox plant named ‘Majestic Magenta’

ABSTRACT

A unique cultivar of Hybrid Creeping Phlox plant named ‘Majestic Magenta’ characterized by vigorous, dense, low spreading, multi-stemmed, winter-hardy habit with short, bright green, linear to awl-shaped leaves. Flowering begins in late-April and continuing for up to four weeks, in cooler weather conditions, on heavily-branched peduncles and completely cover the plant in peak season. Petals have a small notch and the tips and newly opened flowers and mature flowers remain a rich dark-pink color. The new plant is able to withstand dry conditions once established, and the foliage stays clean and resists mildew. The new plant is especially suitable for the landscape as a potted plant and in the garden as a specimen or en masse.

Botanical classification: Phlox hybrid.

Variety denomination: ‘Majestic Magenta’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)

The first non-enabling disclosure of the claimed plant, in the form of a photograph and brief description on a website operated by Walters Gardens, Inc. on Feb. 2, 2020. Subsequently, the new plant was advertised in the “Walters Gardens 20-21 Catalog” by Walters Gardens, Inc. released on May 20, 2020. The claimed plant was first sold to the public on Mar. 16, 2020 by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Phlox ‘Majestic Magenta’ have been sold to the public in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior to the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hybrid Creeping Phlox plant known as Phlox ‘Majestic Magenta’ and will be referred to hereafter by its cultivar name, ‘Majestic Magenta’, or the “new plant”. The new plant was hybridized by the inventor at a wholesale perennial nursery in Zeeland, Mich. on May 9, 2014 as a cross between Phlox subulata ‘Scarlet Flame’ (not patented) as the female or seed parent and Phlox douglasii ‘Cracker Jack’ (not patented) as the male or pollen parent. The new plant passed initial evaluation on the spring of 2017 and was assigned the breeder code 14-415-2 through the remaining evaluation process. ‘Majestic Magenta’ was first asexually propagated by stem cuttings in the greenhouses at the same nursery in Zeeland, Mich. in the summer of 2017. The unique characteristics of the new plant have been found to be reproducible and stable in successive generations of asexually propagated and the resultant plants have been found to be identical to the original selection.

BRIEF SUMMARY OF THE PLANT

Phlox ‘Majestic Magenta’ is unique from all other Hybrid Spring Phlox known to the inventor. The nearest comparison plants known to the inventor include: ‘Rocky Road Magenta’ U.S. Plant Pat. No. 31,485, ‘Rose Quartz’ copending U.S. Plant patent application Ser. No. 16/974,228, ‘Plumtastic’ U.S. Plant Pat. No. 28,896. ‘Rocky Road Magenta’, has flowers of magenta-purple with a small dark eye. ‘Rose Quartz’ is more vigorous spreading and has slightly a taller habit with rose-pink flower color that lightens with maturity. ‘Plumtastic’ has flowers of violet-pink with purple markings near the eye, and the flower initially has a light, near-white center that darkens to the same violet-pink at maturity.

The female parent, ‘Scarlet Flame’, has narrower petals with deeper scarlet flowers with darker spotting near the eye, and the habit is taller and more vigorously spreading. The male parent, ‘Crackerjack’ is slower spreading and shorter in habit and has smaller flowers that are more red with slight orangish tint.

Phlox ‘Majestic Magenta’ differs from and all other Phlox known to the inventor in the following repeatedly observed traits in combination:

-   -   1. Vigorous plants of dense, slowly-spreading habit, spreading         by rooting stems, producing short, clean, glabrous,         bright-green, narrow leaves;     -   2. Multiple heavily-branched stems produce branched panicles;     -   3. Flower beginning in late-April and continuing for up to four         weeks, in cool conditions, nearly completely covering plant at         peak flowering;     -   4. Flowers of rich dark-pink and with small notches at the tip         of the petals;     -   5. Plant is able to withstand dry conditions once established.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the unique traits of Phlox ‘Majestic Magenta’ and the overall appearance of the plant at three-years-old growing in a full-sun trial beds in Zeeland, Mich. The colors are as accurate as reasonably possible with color reproductions. Variation in ambient light spectrum, source and direction may cause the appearance of minor variation in color.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. Phlox ‘Majestic Magenta’ has not been observed under all possible environments. The phenotype may vary slightly with different growing environments such as temperature, light, fertility, soil pH, moisture and maturity levels, but without any change in the genotype. The following observations and size descriptions are based on three-year-old plants in gallon containers grown in a partially shaded greenhouse and also in the full-sun trial garden of a wholesale perennial nursery in Zeeland, Mich. with supplemental fertilizer and water as needed.
